SAND-B OX FOR CARS.

To all whom it may concern:

Be it known that I, WALTER S. ADAMs, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented-a new and useful Improvement in Sand-Boxes for (lars, of which the following is a description.

The object of my invention is to rovide an article of this class that will at al times and under all conditions deliver sand prom tly and efficiently. This object is accomp ished by my invention as is described below. Y

For a more particular description of my invention reference is to be had to the accompanying drawings forming a part hereof, in which,

Figure 1 is a side elevation of my improved box, the lower end of the spout being broken away. Fig. 2 is a sectional view taken on the line 2-2 of Fig. 3 looking in the directionof the arrows. Fig. 3 is a sectional view taken on the line -3-3 of Fig. 1, looking in the direction of the arrows. spective view ofthe swinging gate. Fig. 5 is a sectional view of one end of the swinging gate and a portion of the hopper.

Throughout the various views of the drawings, similar reference characters designate similar parts.

The sand box 1 consists of the hopper 2, the swinging gate 3, and the casing 4 as well as other incidental parts.

The hopper 2 Ais preferably composed of the vertical walls 5, the horizontal flanges 6, and the inclined bottom 7, all of which are preferably as shown in Figs. 2 and 3.

4 The casing 4 is provided with horizontal flanges 8 adapted to rest on the car floor and under the flanges 6. The body 9 of the casing extends vertically from these flanges 8 to inclose the hopper 2 and then contracts to the nozzle 10 to which a pipe may be attached to take the sand to the track. The upper edge of the casing 4 is recessed to form bearings for the trunnions of the gate 3. Stops 12 and 13 are also cast thereon to properly limit the throw of the gate 3 as will appear below.

The gate 3 is provided with trunnions 14 which are journaled in the recesses 11. of the casing 4 and the ends of these trunnions are squared so that either one of them may be provided with a rocking arm or lever 15 which has flanges 16 which are adapted to Specification of Letters Patent.

abut the stops 12- and 13. As this lever is of the conventional form a more detailed description is unnecessary. The sides 17 of the gate 3 extend vertically from the trunnions 14 to the bottom 18 so that when the gate hangs in its normal position this bottom is entirely belowT the level of the lower edges of the hopper 2. The part below the hopper is preferably curved as shown and provided with the inwardly inclined horn 19 which is adapted to stir the sand and keep it finely divided in damp weather. Beyond the curved portion the bottom 13 is provided withlaterally extending flanges on which are a series of transversely disposedridges 20, 21, 22 and 23, each with a sharp peak and of progressively increasing height from the center as shown in Fig. 5, but all the teeth or ridges are below the level of the lower edges of the hopper 2 as set forth above. These ridges serve a double purpose, they keep the san-d from leaking over them when the gate hangs as in Fig. 2, full lines, and break up any lumps that may form in the sand when the gate 3 is thrown as shown in dotted lines. The ridge 23 is far enough removed from the center of the bottom to cause the sand to spill on the inner wall of the casing 4 and further break any lumps should this be necessary.

The gate 3 is thrown by any suitable mechanism attached to the lever 14.

Having thus described my invention, what I claim is,

1. A sand box composed of a ho per, a casing and a gate, said gate having a bottom entirely below the hopper when in its normal position, and provided with laterally extending flanges beyond the lower edges of the hopper and ridges on said iianges.

2. A sand box composed of a hopper, a casing, and a gate, said gate having a bottom entirely below the level of the lowest part of the hopper when in its normal position and provided with laterally extending flanges with ridges thereon running transversely of the gate.

3. Al sand box composed of a hopper, ya casing, and a gate, said gate being provided with a bottom entirely below the level of the lowest portion of the hopper when in its noi'- mal position and provided with laterally extending fianges with ridges thereon of progressively increasing height from the center of the gate.
